22. A. 我们必须记住哪些词汇？B. 我们今天必须记住的词汇有哪些？ Version A - You don't need to ask whether the other person "can tell you" for this question, because if you ask them "which words do we need to memorise today" and they're willing to help, they'll list it out for you. Version B - I added "today" to this question, so it's: "What terms do we have to memorise today?" You can also substitute "today" with "tomorrow" （明天）. Also note that 必须 refers to what must be done and 必需 refers to what one must have. 23.你的开车技术如何？24. 你做饭的技术如何？27. 你的老师的汉语口语如何？ Instead of asking "are your X skills good", asking "how are your X skills" makes the question more open ended, so I would suggest using 如何. Another example of using 如何 is "我们该如何学习做菜？" (how should we learn how to cook). As for why I put 的 in different places, I did what sounds natural to me. 25. 你在这个教师里认识的人多吗？ The correct way to use "多(verb)" is to say ”你该多交些朋友“ (you should make more friends). So, to avoid sounding like you're making a suggestion of something, you can rephrase it to "你在这个教师里认识的人多吗？" 26. 一个人旅行会危险吗？一个人旅行有多危险？一个人旅行会遇到什么危险？ Is it dangerous to travel alone? How dangerous is it to travel alone? What are the dangers of traveling alone?
